WCSH-TV reports Jacob was diagnosed at age 5 with stage 4 neuroblastoma, a cancer that starts in the nerve cells and generally affects infants and young children.
The TV station says Jacob's family will decorate his hospital room with a Christmas tree, lights, and fake snow. Santa Claus also will be there.
Roger Guay says his son loves getting Christmas cards and is particularly fond of homemade cards.
The cards should be sent to:
